Abstract:

A series of tests of a portable Raytheon DE-723B fathometer were made in the Anacostia and Potomac Rivers to evaluate over-the-side and through-the-hull transmission at various speeds. The over-the-side transducer mount provided high resolution at speeds up to 10 knots. Transmission through the steel hull of an LCM-6 Landing Craft Medium is feasible at speeds up to 3 knots using maximum sensitivity settings. Location of the transducer over-the-side near the pilot house and rigged to minimize vibration is recommended for surveys using LCM-6 craft.
